F7 and ePM1: check the declared classification

These replacements state ePM1 60% as well as F7. F7 belongs to the former EN 779 system; ePM1 expresses the efficiency group under ISO 16890. Read what F7 means to understand why the classifications are not automatic equivalents.

Is F7 + F7 the same as F7 + G4?

No. This set has two fine filters. Do not substitute a G4 element simply because another ventilation unit uses that combination.

How often should HENCO filters be replaced?

ZenAero's guide uses 4–6 months as an orientation for many residential installations, not a universal interval for this set. Follow the manual and assess each element and the air conditions; a damaged or heavily loaded filter may need earlier replacement. See replacement intervals and how to change ventilation filters.

These are ZenAero compatible replacements, not original HENCO filters. Check the supported models, pack contents and availability on each product page. For another brand, browse the ventilation filter catalogue.
